The apps they mention are fine, but watch out for one important thing: a lot of public chargers are outdated on all the platforms, so even if the app tells you there's one available 2km away, when you get there it's just as likely to be broken or out of service! What I'd do is start by checking whether your city council or regional government has an official map of charging points, because those tend to be more up to date than private apps. And then yeah, combine PlugShare with whatever your local operator tells you (a lot of cities have their own local operators) and check the recent reviews to see which one's actually working, not just in theory.
